Apparatus and method for two-sided printing

Image Number 2 for United States Patent #5899615.

An apparatus and method for two-sided printing on items such as mail pieces. A printing station includes an ink jet printhead which is spaced from a transfer roller. As the roller rotates the printhead forms a first image on the surface of the roller. A mail piece or other item to be printed is feed through the printing station to pass between the printhead and the roller with the timing control so that the mail piece makes tangential, rolling contact with the transfer roller just as the image is completed on the roller and the image is then transferred from the roller to one side of the mail piece as the mail piece continues through the printing station by an offset printing process. As the mail piece passes between the roller and the printhead the printhead is controlled to print a second image on the opposite side of the mail piece.
